Jack and Jill are working on a presentation based on PPT-slides. Jill is good at preparing slides but less good at presenting slides to the public, whereas Jack is good at presenting slides but less good at preparing slides. As Table 1 shows, Jack needs 50 minutes to prepare one slide but only 10 minutes to get ready for a speech that explains the content of a slide to audiences. Whereas, Jill only needs 10 minutes to prepare one slide but needs 50 minutes to get ready for a speech until she gets comfortable with presenting the slide.

Each of them needs to prepare a 10-slide presentation. The lower part of Table 1 shows what is likely to happen if they do not divide the labor and work on their own. Table 2 shows what is likely to happen if they trade by dividing the labor and working in a collective manner. Using your knowledge of absolute advantage and comparative advantage to explain the benefit of trade between Jack and Jill in terms of working on the 10-slide presentation.
